Damage caused by weather events has increased dramatically across the world in recent years. In the case of Japan, record-breaking rainfall has caused devastating damage almost every year since 2014; many people have been killed in these disasters. To better prepare for future heavy rainfalls, we need to discover how to prepare for disasters and mitigate damage by learning from examples in resilient communities. In 2017, torrential rains hit Toho Village in northern Kyushu, and the people as a whole responded well to avoid disastrous outcomes. We studied the actions and motivations of residents of Toho during this rainfall event by conducting semi-structured interviews in November 2017. The interviewees indicated that their motivation for evacuating was “personal observation of the danger” or “communication with neighbors”. Communication within the community was found to be an important factor that enabled the safe evacuation of community members, even without notice of the disaster risk and/or in the absence of timely information from the government because of a power outage. Knowledge of local landforms would be also helpful to reinforce appropriate actions and precautions needed during a disaster.

本研究では,内水氾濫と外水氾濫が同時に発生する複合水害について,下水道が機能せず,1000年確率降雨の条件で重畳氾濫シミュレーションを香川県高松市の二級河川御坊川を対象として実施した.その結果,内水氾濫と外水氾濫を個別に考慮する場合と比べて,複合水害では,浸水範囲が増加し,流速も部分的に速くなることが分かった.そのため,避難の難易度が上がることが想定され,水害のハザードマップに重畳氾濫を想定することが今後必要である結果が示された.

本研究は,香川県内企業の防災対策と事業継続計画の取り組み状況,2016年4月に発生した熊本地震による影響をアンケート調査により明らかにした.結果,事業継続対策の取り組みに進展が見られるものの計画策定内容は未だ十分なものでなく,あらためて事業継続計画の基本的な考え方等についての啓発の必要性が明らかとなった. 調査は,2008年9月,2012年2月の継続調査であり,経年変化とともに全国的なトレンドとの比較を行った.加えて,2011年3月に発生した東日本大震災と熊本地震の影響を比較することにより,狭域被害となる直下型地震と広域被害の海溝型地震による災害形態の影響と産業別事前復興の必要性について考察した.
